3.0 Installation • Design Considerations and Prechecks
3.0 Installation
WARNING
!
Improper installation, adjustment, alteration, service or maintenance can cause
property damage, serious injury or death.
Read and understand, the installation, operating and maintenance instructions
thoroughly before installing or servicing this equipment.
Only trained, qualified gas installation and service personnel may install or service
this equipment.
Design Considerations and Prechecks
Placement of infrared heaters is influenced by many factors. Aside from safety factors, considerations
such as the number of heater or vent elbows that are allowed, maximum vent lengths, ducting of
combustion air and combining exhaust vents are a few examples. All installation manuals, along with
national, state, provincial and local codes, address these issues. It is critical that you read, understand
and follow all guidelines and instructions.
To ensure a properly designed heating system, a layout should be developed for the correct placement of
the burner control box, tubes, vents and combustion air intake ducts. Inspect and evaluate the mounting
conditions, vent locations, gas supply and wiring.
When designing an infrared radiant heating system, consider the following:
• Has the building’s heat loss been evaluated?
• Does the design meet the needs of the space?
• Have recommended mounting heights been observed?
• Have all clearance to combustibles situations been observed?
• Is the supply (burner) end of the heater located where more heat is required?
• Is it best to offset the heaters and/or rotate the reflectors towards the heat zone?
• Are extra guards, side shields, ‘U’ or ‘L’ reflector covers required?
• Does the heater require outside fresh air for combustion?
• Is the environment harsh or contaminated (requiring outside air for combustion)?
• Are chemicals or vapors a concern (requiring outside air for combustion or additional ventilation)?
The effective infrared surface temperature of a person or object may be diminished with wind above 5
mph. The use of adequate wind barrier(s) may be required.
IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater. This
distance may exceed the published clearance to combustibles as posted on the heater. Certain
applications may require the use of high temperature sprinkler heads or the relocation of the heaters.
Sprinkler systems containing propylene glycol or other flammable substances are not to be used in
conjunction with this heater without careful consideration for and avoidance of potential fire hazards. For
further information, consult NFPA 13.

AG2 Series

Factory recommended mounting heights are listed as a guideline. If infrared heaters are mounted too low
or too high, they may result in discomfort or lack of heat. Brant Radiant Heaters Ltd. generally
recommends observing the recommended mounting heights to optimize comfort conditions. However,
certain applications such as spot heating, freeze protection, outdoor patio heating or very high ceilings
may result in the heaters being mounted outside of the factory recommended mounting heights.

is achieved. Chains must be straight up and down. Do not install chains at an angle as this can result
in tube warping or separation.

Radiant Tube Assembly
To install the radiant tubes:
Place tubes in hangers with the welded seam facing downward and the swaged end of the tube
towards the exhaust end of the heater system (see figure 3.6).
Refer to page 23 for tube installation sequence. Place the combustion chamber as the first tube
connected to the burner control box. Models 150 MBH utilize a titanium combustion chamber with
yellow identification tag.

IMPORTANT! 150,000 BTU/h models must be installed with a
stainless steel tube clamp (P/N: TP-220) located at the seam
between the primary combustion chamber and the second tube
section downstream of the burner control box.
NOTE: If the tube clamp comes
apart, the spacer must be
re-assembled with the spacer’s
concave surface facing against
the radiant tube surface.

Optional Elbow or U-Bend Accessory Configuration
A 90 degree elbow or 180 degree U-bend accessory fitting may be installed in the radiant tube heating
system. Refer to Chart 3.3 for minimum distance requirements from the burner control box.
When installing an Elbow or U-Bend Accessory Fitting:
• The top clearance of an uncovered (no reflector) elbow or U-bend accessory fitting to combustibles
is 18 in.
• If operating the heater unvented, separate the intake air to the heater from its exhaust products a
minimum of 4 ft., further separation may be necessary. Combustion air may also be supplied.
• A maximum of two 90° elbows or one 180° U-bend can be installed on a heater.
• Omit one 36 in. section of turbulator baffle. Refer to Baffle Assembly section.
3 Slip-fit the radiant tube sections together until tightly connected (install the swaged end of each tube
towards exhaust end). NOTE: If it is difficult to mate the tubes, they may be installed incorrectly.
4 Center tube clamps over the seam where two radiant tube sections connect. If necessary, rotate tube
clamps so they will not interfere with the reflector end caps during expansion and contraction of
the heater.
Tighten tube clamp bolts to secure. When proper compression is obtained (40-60 ft-lbs. torque) the
tube seam will create a visible mark on the tube clamp. NOTE: Excessive torque may damage the
tube clamp.
6 Determine the location of the burner control box and note the placement of the mounting chains.
Figure 3. 8 • Tube Connections
Tubes fit snuggly together and the
tube clamp is centered over the seam.
Tubes are not fit snuggly
together and the tube clamp is

The tube clamp is tight when the
torque is achieved (normally
when seam becomes visible).

To install the reflectors (see figure 3.14):
Attach the reflector center supports onto radiant tubes. NOTE: On models equipped with a single
reflector center support, place at mid-point of primary combustion chamber.
2 Slide each reflector section through the hangers and adjust the reflector tension spring (if applicable)
into the V-groove on the top of the reflector. The reflectors should overlap approximately 4 inches.
3 To prevent the reflectors from shifting, secure the reflector sections together using sheet metal screws,
except at the expansion joint (see page 23). NOTE: Installer to supply sheet metal screws.
4 Attach reflector end caps (if applicable), with polished finish inward, to each end of the reflector run.
Secure with clips.
Reflectors, and reflector accessories, direct infrared energy to the floor level. The reflector assembly
depends on the heater configuration, proximity to combustibles and space surrounding the heater.
Before you begin assembly, determine if the use of reflector accessories are necessary (see chart 3.5).
